ABSTRACT:
An automatic variable speed lever action drive for a pedal operated vehicle, in which a pedal lever pivotally mounted on each side of the vehicle frame is connected in part by an extensible and retractable cable to a driven wheel, the lever having a direct driving connection to the cable through a roller on a tension spring for deflecting the cable to varying degrees in accordance with the tension load on the cable. The lever has a knee joint type double pivot and is guided through the actuating stroke to substantially linearize the actual path of the pedal.
